We look at the division of 864903 by 91 
Let's see how many times 91 fits into 864903.

Let's proceed to step 1:
91 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 91

Advancing to step 2:
If we divide 86 by 91, we get 0 and a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (4) from the dividend to 86 and continue with: 864 / 91

On to step 3:
864 divided by 91 is 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 819 from 864 to get 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 91

Going ahead to step 4:
The number 91 fits into 459 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
If we take 455 away from 459, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 91

Step 5:
91 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 950.0
If we subtract 0 from 40, we get 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 91

Let's proceed to step 6:
403 divided by 91 is 4 with a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 9504.0
Subtracting 364 from 403 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
91 goes into 390 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 9504.4
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
91 can be fit into 260 2 times, resulting in a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 9504.42
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 9:
780 divided by 91 is 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 9504.428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
If we divide 520 by 91, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 9504.4285
If we take 455 away from 520, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
If we divide 650 by 91, we get 7 and a remainder of 13.
The next digit of our result is 7. 
Result so far: 9504.42857
If we subtract 637 from 650, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
91 goes into 130 1 times with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 9504.428571
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
If we divide 390 by 91, we get 4 and a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 9504.4285714
Subtracting 364 from 390 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
The number 91 fits into 260 2 times, leaving a remainder of 78.
The next digit of our result is 2. 
Result so far: 9504.42857142
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 9504.42857142 and a remainder of 7.8e-08.
